If my choir is performing a song from a film or play I always like to put the piece in context, which often means that I have to wade through summaries of plots that make very little sense. Many if not most musical comedies have plots that are simply frameworks, often flimsy, to hang the song-and-dance numbers on. (It’s okay for me to end that previous sentence with a proposition since one of these song titles does that, too.) Also, sometimes the musical numbers have outlived the production for which they were written and it’s very difficult to get access to the original story.
